The Space Shuttle Discovery took its final flight this morning from Florida to Washington, DC on the back of one of NASA's 747 carrier planes used to carry the space shuttle's around the country. I went down to the National Mall this morning and stood in front of the Washington Monument to photograph its many fly-overs it took before making its final landing at Dulles International Airport where it will be put on display in the Smithsonian National Air & Space Museum, at the Udvar-Hazy Center.
Below are what I think are some of my best shots I got with my 28-300mm lens (which on my crop sensor camera, turns into a 480mm zoom).
Approaching over the Lincoln Memorial.

Nice side shot with the NASA T-38 in frame.
Another good side shot.
Flying almost directly overhead.
Washington Monument flags in the foreground.
Coming out from behind the Washington Monument.
With the White House in the foreground.
Another pass with the White House in view.
Another good side shot from close underneath during its last pass.
And while I did not take this picture, I could not resist posting this awesome shot that was posted on the NASA HQ Flickr account:
Also, here is a video from my friend Ted Severson shot from the steps of the U.S. Capital building this morning:

Finally, here is a slideshow of the entire 284 photos I took and posted on Flickr:
